Improvement in stove-pipes



UNITED STATES PATENT QEEIo HENRY L. PALMER, OF NEW YORK, N. Y.

IMPROVEMENT IN STOVE-PIPES.

Specification forming part of Letters Patent No. 136,755, dated March 11, 1873.

To all whom it may concern:

Be it known that I, HENRY L. PALMER, of the city, county, and State of New York, have invented certain Improvements in Stove-Pipes, of which the following is a specification:

The principal part of my invention relates to the construction of joints of stove-pipes in such a manner that they may be easily put together or taken apart, and also with especial reference to shipping the same in large quantities to the retail dealers throughout the various parts of the country.

In the accompanying drawing, Figure 1 is an elevation of the two ends of a joint of stovepipe embodying my invention. Fig. '2 is a horizontal section of the same taken on the plane of line y y in Fig. 1. Fig. 3 is an elevation of the small end of the pipe, each section thereof being separated.

My invention consists in making a joint of stove-pipe in longitudinal sections,- which are so constructed as to be easily put together when required for use.

A is the small end of the pipe, the two sep' arate sections of which are c and d. Upon one section, 0, I form the beads on a of a circular form and of about three-eighths of an inch in diameter. On the edges of the other section d I form smaller beads 11 b. The relative sizes and forms of beads a c and b b are shown in Fig. 2. The small end of section dis extended so as to form a lap, e, which passes under the small end of section 0 in or der to form a tight joint at the small end of the pipe. At the large end of the pipe the beads a a and b b are continued down to the bottom of the joint, as shown at B in Fig. 1.

Joints of pipe made according to my invention may be made of smaller pieces of sheet iron, such as are cut from the sheets in making larger articles.

For shipping large quantities of pipe in a compact form, for taking down pipe in the spring or at other times to clean it, or to stow pipe in the summer when not in use, my invention supplies a want not heretofore provided for, and the utility of which none can deny.

It is evident that beads a a and b I) need not necessarily be made circular inform, but as this can be as easily made perhaps as almost any other, and as it looks better, I therefore prefer it as shown in Fig. 2.

' What I claim as new, and desire to secure by Letters Patent, is

A joint of stove-pipe constructed in sections 0 and d, and having beads or locks a a and b I) fitted to slide into each other, for the purpose herein shown and described.

- HENRY L. PALMER.
